Agriodor closes €15M round led by Crédit Mutuel Impact



The Rennes-based INRAE spin-off uses blends of volatile organic compounds to repel or attract pest insects without harming pollinators, soil, or human health. Its first product, for sugar beet aphids, received French regulatory authorisation in March 2026 and is distributed by Syngenta.


Agriodor, a French deeptech startup specialising in olfactory biocontrol, has raised €15 million in a round led by Crédit Mutuel Impact.

The Rennes-based company, founded in 2019 as a spin-off from INRAE, France’s National Research Institute for Agriculture, Food and Environment, develops blends of natural volatile organic compounds that exploit insects’ olfactory sensitivity to repel pest species from crops, without harming pollinators, auxiliary insects, or human health.

Agriodor’s approach targets a fundamental behaviour in insect biology: approximately 80% of the world’s invasive insect pests use smell to locate host plants for feeding, mating, and egg-laying.

By analysing the compounds emitted by plants that insects find unattractive, and replicating those molecules synthetically, the company produces fragrances that confuse or deter specific pest species.

These can be deployed as attractants (kairomones, which lure insects into traps) or repellents (allomones, which drive them away), or combined into a push-pull strategy using both modes simultaneously. The products are formulated as granules spread mechanically across fields, making them compatible with existing farm machinery.

The company’s most advanced product targets Myzus persicae, the green aphid responsible for spreading yellowing disease in sugar beet, a crop that lost its main chemical protection when neonicotinoids were banned across France and Europe.

Agriodor’s olfactory repellent, marketed as INSIOR® Gr A in partnership with Syngenta, received French regulatory authorisation for field trials in March 2026. Field trials conducted by Syngenta in 2025 showed a 40% reduction in green aphid populations compared to untreated controls.

The product acts through three modes simultaneously: it repels winged aphids responsible for field colonisation, disrupts their feeding behaviour, and reduces their reproductive rate by limiting energy intake.

Prior to this round, Agriodor had raised approximately €8 million across two tranches: a €5 million round in May 2023 from Capagro, Cap Horn, BNP Paribas Développement, SWEN Capital Partners, and Breizh Up; followed by a €3 million extension from the same investors in February 2024.

In December 2025, Le Journal des Entreprises reported that Agriodor was seeking exactly €15 million for three new products across additional crops, expanded geographical coverage including tropical zones, and new global distribution partnerships.

The company is headquartered in Rennes and targets the US and Brazilian markets, where biocontrol regulations are substantially faster than in Europe, 18 to 24 months for market authorisation versus up to seven years in the EU.

Co-founder and CEO is Alain Thibault; CTO is Dr Ené Leppik, a chemical ecologist whose doctoral research on the bean weevil at INRAE provided the scientific foundation for the company.

Crédit Mutuel Impact is the dedicated impact investment arm of Crédit Mutuel, France’s second-largest banking group, which was founded by farmers and retains a strong agricultural heritage.

An impact-oriented agricultural investor leading a round into a biocontrol startup replacing banned insecticides fits squarely within Crédit Mutuel’s stated priorities around sustainable food systems.

Do you ever walk past a person on the streets exhibiting mental health issues and wonder what happened to their family? I have a brother—or at least, I used to. I worry about where he is and hope he is safe. He hasn’t taken my call since 2014.

When I was 13, I had a very bad day. I was in the back of the car, and what I remember most was the world-crushing sound violently panging off every surface: he was pounding his fists into the steering wheel, and I worried it would break apart. He was screaming at me and my mother, and I remember the web of saliva and tears hanging over his mouth. His eyes were red, and I knew this day would change everything between us. My brother was sick.

Nearly 20 years later, I still have trouble thinking about him. By the time we realized he was mentally ill, he was no longer a minor. The police brought him to a facility for the standard 72-hour hold, where he was diagnosed with paranoid delusional schizophrenia. Concluding he was not a danger to himself or others, they released him.

There was only one problem: at 18, my brother told the facility he was not related to us and that we were imposters. When they let him out, he refused to come home.

My parents sought help and even arranged for medication, but he didn’t take it. Before long, he disappeared.

My brother’s decline and disappearance had nothing to do with the common narratives about drug use or criminal behavior. He was sick. By the time my family discovered his condition, he was already 18 and legally independent from our custody.

The last time he let me visit, I asked about his bed. I remember seeing his dirty mattress on the floor beside broken glass and garbage. I also asked about the laptop my parents had gifted him just a year earlier. He needed the money, he said—and he had maxed out my parents’ credit card.

In secret from my parents, I gave him all the cash I had saved. I just wanted him to be alright.

My parents and I tried texting and calling him; there was no response except the occasional text every few weeks. But weeks turned into months.

Before long, I was graduating from high school. I begged him to come. When I looked in the bleachers, he was nowhere to be seen. I couldn’t help but wonder what I had done wrong.

The last time I heard from him was over the phone in 2014. I tried to tell him about our parents and how much we all missed him. I asked him to be my brother again, but he cut me off, saying he was never my brother. After a pause, he admitted we could be friends. Making the toughest call of my life, I told him he was my brother—and if he ever remembers that, I’ll be there, ready for him to come back.

I’m now 32 years old. I often wonder how different our lives would have been if he had been diagnosed as a minor and received appropriate care. The laws in place do not help families in my situation.

My brother has no social media, and we suspect he traded his phone several years ago. My family has hired private investigators over the years, who have also worked with local police to try to track him down.

One private investigator’s report indicated an artist befriended my brother many years ago. When my mother tried contacting the artist, they said whatever happened between them was best left in the past and declined to respond. My mom had wanted to wish my brother a happy 30th birthday.

My brother grew up in a safe, middle-class home with two parents. He had no history of drug use or criminal record. He loved collecting vintage basketball cards, eating mint chocolate chip ice cream, and listening to Motown music. To my parents, there was no smoking gun indicating he needed help before it was too late.

The next time you think about a person screaming outside on the street, picture their families. We need policies and services that allow families to locate and support their loved ones living with mental illness, and stronger protections to ensure that individuals leaving facilities can transition into stable care. Current laws, including age-based consent rules, the limits of 72-hour holds, and the lack of step-down or supported housing options, leave too many families without resources when a serious diagnosis occurs.

Governments and lawmakers need to do better for people like my brother. As someone who thinks about him every day, I can tell you the burden is too heavy to carry alone.
